Method for planting lycium ruthenicum in saline-alkali soil and improving soil and fertilizer statuses

Abstract

The invention discloses a method for planting lycium ruthenicum in saline-alkali soil and improving soil and fertilizer statuses. The method comprises the steps: improving fertilizer addition and landpreparation; ridging; timely seeding; field management; shape pruning; and harvesting and processing, wherein an improving fertilizer comprises desulphurization gypsum, activated carbon, coal ash, poultry excrements, zeolite, potassium feldspar, felt fiber and blast furnace slag particles which are in the weight ratio: (40-50):(10-14):(8-12):(8-12):(4-8): (4-8):(4-8):(4-6). In the method, the lycium ruthenicum is planted by improving the saline-alkali soil by using the improving fertilizer and a drip irrigation system, the survival rate and yield of the lycium ruthenicum are high, the effecton improving the whole saline-alkali soil is remarkable, and the improving process is green, environment-friendly and pollution-free. Therefore, the method is an application technology worthy of beingpopularized on a large area.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land transformation, in particular to a method for planting wolfberry black fruit and improving soil and fertilizer conditions in saline-alkali land. Background technique [0002] At present, there are mainly the following technical measures for the transformation of saline-alkali land: [0003] 1. Water conservancy improvement, salt washing with fresh water: suitable for well-drained areas with high terrain. [0004] 2. Biological improvement: improve the micro-ecological environment of saline-alkali land, apply bio-organic fertilizers, supplement organic matter, and increase the number of beneficial microorganisms in the soil, so as to establish a new micro-ecological balance between soil, plants and microorganisms in saline-alkali land, and achieve the goal of biological control. [0005] 3. Chemical improvement: apply about 15 tons of gypsum per hectare, and apply it once as a base fert...

Problems solved by technology

The soil is not strictly required. The salt content of the background soil can reach 8.9% in the 0-10cm soil layer, 5.1% in the 10-30cm soil layer, and 2.5% in the rhizosphere soil. Salt-alkali tolerance is extremely strong, and it has a strong salt-absorbing ability; the ability to resist waterlogging is poor, and it is not suitable for planting in low-lying water.
